FRANK HOLUB AND CHARLES S. LOCKE, OF CHICAGO, ILLINOIS.

MACHINE FOR MAKING BARS FOR HORSESHOE-BLANKS.

SPECIFICATION forming part of Letters Patent No. 242,534, dated June 7,1881.

Application filed September 21, 1880.

To all whom it may concern:

Be it known that we, FRANK HoLUB and CHARLES S. LOGKE, both of Chicago.in the county of Cook and State of Illinois, have invented certain newand useful I mprovenients in Machinery for Making Horseshoe-Blanks,

y of which the following is a specification.

It is our purpose in devising` this` machinery to provide for themanufacture of connected series of horseshoe-blanks from old, worn, orrefuse steel rails, or from erop ends ot' rails, which can be cheaplyvobtained, and which furnish stock of excellent quality and of'approximate shape for the purpose. Stich rails are of varying dimensionsin cross-section, and it is our purpose to construct a single machineadapted to accommodate their dili'ercnt sizes. We have heretoforepatented a machine in United States Patent N o. 227,010 for formingseries of horseshoe-blanks from the base portions of such rails; but ourpresent invention relates to forming series ot' horseshoeblanks from thetop portions of such rails.

In the accompanying drawings, Figure 1 is a front elevation of so muchof a set ot threehigh rolls as is necessary to illustrate our invention,which consists in the combinations of particular parts l'oraccomplishing the objects above stated, as hereinafter definitelyexpressed in our claims.

In this ligure, 1, A indicates the middle roll, B the upper roll, and Cthe lower roll, which rotate in the directions indicated bythe arrows.These rolls we have provided with various peculiar dies, as follows:

a indicates the initial annular die in roll A, of the outline incross-section clearly shown at a', and a2 indicates a coincident annulardie in roll C, of rectangular cross-section.

b indicates an annular die in roll A, of rectangular cross-section, andb a coincident annular die in roll C, ot' the outline in cross-sectionclearly shown at b?.

c indicates an annular die in rollA, of rectangular cross-section, and ca corresponding rectangular die in roll B'.

(No model.)

f indicates an annular rectangular die in roll C, and coincident with itin the roll A is the calk-die k.

g indicates an annular die in the roll A, of angular. cross-section, soas to form the shoulder g2, and g4 indicates an annular concave die inthe roll B.

The dies just described, in some instances, as will be perceived by thedrawings, being opposite to and operating in conjunction with the plainsurfaces of one or other ot the coincident rolls, are designed to form asingle series of horseshoe-blanks from an upper section of either alarge or a small-sized steel railroadrail ot' the ordinary form known asT-rail at a single heating ot' the section or billet. Such a portionot'a rail is shown in cross-section in Fig. 2, and, as will be perceived,it embraces the tread and a part ot' the web of the rail, the lowerportion ot' the web and the iianges, as indicated in dotted lines, beingremoved. It will be noted that eight passes through the rolls areprovided for, starting at No. l from the front of the rolls, and thesepasses would all be necessary it' a large-sized rail-billet should beworked to form a single series ot' blanks; but ordinarily only thesmaller-sized rail-billets would be used to forma single series ofblanks, and in that case only seven passes through the rolls would berequired, cominencing at No. 2 fromthe rear. Suitable guides andsupports being provided in front and rear ot' the rolls, as usual, ifdesired, and the rolls being in operation, revolving in the directionindicated by the arrows, and a smallsized railbillet being properlyheated and passed through the rolls at No. 2, it would be given theshape in cross-section shown in Fig. 3. Beingthen returned through therolls at N o. 3, itwould be further reduced and rendered more nearlyrectangular in crosssection. Being next passed throughat No. 4, it wouldbe made square in cross-section. Being next returned at No. 5, it wouldbe reduced and elongated, but remain square. Being next passed throughat No. 6, it would be formed into an angle-bar, as shown incross-section in Fig. 6. Being next returned at No. 7, it would beformed into a rectangular calked bar, as shown in Fig. 8. Being finallypassed through at No. 8, it would emerge in front of the rolls acompleted series of horseshoe-blanks with the IOO calks elongated andthe front edge rounded, as shown in Fig. 9. The diameter of the rollsand the position of the calli-dies k and k must, of course, as usual, besuch that the ealks will be formed at the proper distance apart for ahorseshoe ot' given size, so that the series of blanks can be cut intosingle blanks at equal distances between the calks.

As it may frequently bel convenient to alternately pass through largeand small sized rail-billets, it is a matter of' considerable economy toprovide for it in the same machine, and accordingly we have made, inconnection with the devices just described, in the same set of rolls thefollowing dies and cutters for making simultaneously two series ofhorseshoe-blanks from a single large-sized rail-billet.

In Fig. 1, m indicates an annular die of rectangular cross-section inthe roll B, coincident with the die b in the roll A.

a indicates an annular die, and n a cutter projecting from its center,in the roll A.

'n2 indicates an annular rectangular die in the rollt), and a3 a convexprojection from its center, both being coincident with the die n andcutter a.

o indicates an annular rectangular dic in the roll A, and o a convexprojection from its center.

o2 indicates an annular rectangular die in the roll B, coincident withthe die 0, and 03 a cutter projecting from its center and meeting theconvex projection o.

p p indicate annular dies in the roll A, o' angular cross-section, so asto form shoulders 192193.

q q indicate annular dies in the roll B, reetangular in cross-section,and the calk -dies k and k are coincident with them, so as lo prop erlvdo the calkinn.

The annular dies g and g in the roll A, ot' angular cross-section, so asto form shoulders g2 g, are designed to linish the two series ot' blanksand elongate the calks, while working in conjunction with the annularconcave dies 1' r in the roll C to round the edges ofthe series ofblanks.

The dies and cutters just described, including Nos. 1 and 2, as will beperceived, provide for nine passes of the billet through the rolls,beginning at No. 1 from the front. The

first pass will somewhat compress and reduce the billet, and the returnpass at No. 2 will give it the form in cross-section shown in Fig. 3.The next pass through at No. 3 will bring it nearer to rectangular formin crosssection, and the return at No. 4Lx will perfect its rectangularoutline, as shown in Fig. 4. Tile next pass, at No. 5x, will partiallysever it longitudinally in the center, as shown in Fig. 5, and thereturn at No. 6L will complete the severance, as shown in Fig. 6. Thetwo equal parts x and y are next passed through at No. 7 x and given theform in cross section shown in Fig. 7, and the return at N o. 8X willform the calked blank, as shown in Fig. 8. Finally, the pass at No. 9xwill finish the two series of blanks and elongate the calks and roundtheir front edges, as shown in Fig. 9.

Vith this construction it will be perceived that a large railbillet maybe entered at No. 1, and after it has passed No. 2 a smaller billet maybe entered there, and the two may proceed on theirrespective coursesthrough the rolls, both undergoing the process of manufacture at thesame time, and the next billet that is entered in the machine may eitherbe a large or small one. All that will be necessary is that, forconvenience of working, the small billets be placed in rear of themachine for heating and delivery there and the larger billets be placediu front of the machine for the same purpose.

Having thus described the construction and mode of operation of ourinvention, what we claim as new, and desire to secure by Letters Patent,is- V l. The combination, in a set ot' rolls, of the dies at Nos. 1, 2,and 3 with those at Nos. 4*, 5x, 6X, 7X, 8K, and 9X, including thecutters and projections at Nos. 5x and 6X, and with those at Nos. 4, 5,6, 7, and 8, substantially as shown and described, whereby a rail-billetofthe crosssection shown in Fig. 2, oflarge size or of slnall size, maybe entered at will and both be undergoing manufacture at the same timein one set ot' rolls.

2. The combination of the dies at Nos. 1, 2, 3, 4X, 5X, 6X, 7x, 8X, and9X, including the cnt ters and projections at Nos. 5x and 6x,substantially as shown and described, whereby two series of'horseshoe-blanks may be simultaneously formed from a rail-billet of thecross section shown in Fig. 2.
